Hooked on a Feeling was first recorded by B.J. Thomas in 1968, but the version everyone recognises is Blue Swede's 1974 cover, which added the distinctive ooga chaka chant and topped the charts in the United States. Decades later it returned to global attention through the Guardians of the Galaxy soundtrack, where its retro optimism perfectly matched Star-Lord's mixtape era. Since then it has lived on in dance videos, lip-syncs and meme edits, because the chant alone signals instant joy and old-school cool.
